In a small bowl, stir together the tomatoes, 1 tablespoon of the shallot, and half of the cilantro. Set aside.

Melt the butter in a medium saucepan. Once melted, add in the remaining shallot, salt, and the jalapeno and saute for 3 minutes. Stirring often.

Pour in the flour and cook until the flour is completely absorbed, about a minute.

Whisk in the milk and then bring to a light simmer. Stirring often, let the mixture cook for about 5 minutes until it has thickened considerably.

Stir in the cheeses and continue stirring until all of the cheese is melted. Stir in the remaining cilantro.

Pour into a serving bowl and top with the tomato mixture. ENJOY!!
